How are life insurance death benefits generally treated for federal income tax purposes?

Life insurance death benefits paid to a beneficiary are generally received free of federal income tax when paid as a lump sum. This favorable tax treatment is a key advantage of life insurance. There are nuances: if the benefit is paid in installments, the interest portion may be taxable; very large estates may face estate tax considerations depending on policy ownership; and certain transfer-for-value situations can affect taxation. But the general rule — that the death benefit itself is income-tax-free to the beneficiary — is a commonly tested point. (Tax rules can change and individual situations vary, so this reflects the general principle.)
